Highly reflective mirror technologies are majorly required in bio-sensing applications to eliminate complex multiple diffraction orders. In this paper, various grating parameters, i.e. width, thickness, and period are analyzed to get optimized values and high reflectivity for high-contrast subwavelength grating (HCSG) structure. Besides these parameters, polarization modes, angle of incidences, and refractive index have been diversely analyzed to monitor their effects on HCSG structure with respect to reflectivity. The simulation results manifest that the optimized parameters help to achieve the best reflectivity that can be further utilized in bio-sensing applications.
